5. Warning
function
Door alarm : Leave the outer door open and DP54 (red lamp) is lit. Buzzer beeps
intermittently after 1~15 min. (Door alarm setting time) has passed. Initial
setting time is 2 min. Buzzer does not activate simultaneously with
remote alarm terminal output. Once press BUZZER key to stop buzzer
beeping, buzzer does not beep again unless alarming condition get
backs.
High temp. alarm : When PV is reached at SV+SV
H
(high temp. alarm SV) +1 or higher,
ALARM lamp and LED display blinks, intermittent buzzer beeps with
approx. 15 minutes of delay and remote alarm output turns on.
When PV is reached at SV+ SV
H
or lower, ALARM lamp and LED display
go off, buzzer stops beeping and remote alarm output turns off.
If you press BUZZER key, the buzzer stops beeping instead remote
alarm output does not turn off.
Low temp. alarm :
When PV is reached at SV-SV
L
(low temp. alarm SV) -1 or lower, ALARM
lamp and LED display blinks, intermittent buzzer beeps with approx. 15
minutes of delay and remote alarm output turns on.
When PV is reached at SV- SV
L
or lower, ALARM lamp and LED display
go off, buzzer stops beeping and remote alarm output turns off.
If you press BUZZER key, the buzzer stops beeping instead remote
alarm output does not turn off.
Filter blockage : With the filter sensor temperature is reached at 48.0
㷄
or higher, FILTER
lamp is lit with buzzer beeps intermittently.
With the filter sensor temperature is reached at 43.0
㷄
or lower, FILTER
lamp goes off and buzzer stops beeping.
6. Other
function
Cascade
control : Compressor (L) is allowed to turn on when the cascade sensor
temperature is reached at -34.1
㷄
or lower during pull-down.
Compressor (L) is allowed to turn off when the cascade sensor
temperature is reached at -12.0
㷄
or higher during pull-up.
Auto Return :
If there is not any key operation for 90 seconds in each setting mode,
Key Lock mode and Function mode, automatically reverts to PV mode.
Note) Auto Return is not worked in F09 and F10.
